MTBE: Relationships

Every element and industry that MTBE is linked to, and how. Each pair has its own card explaining the relationships between the two.

• Bioethanol: Ethanol and MTBE compete for the same job in petrol: adding octane and oxygen. The US switched from MTBE to ethanol in 2006 after groundwater contamination, and India's 20% ethanol blending, reached in 2025, leaves less room for octane ethers. (researched)
